Abstract
The utility model discloses a multifunctional die-dismounting pull hammer which comprises a pull rod, a hollow cylinder sleeve, a screw cap, a nut and a dowel screw. The hollow cylinder sleeve is sleeved outside the pull rod, the screw cap is fixed at the top end of the pull rod, the nut is connected with the lower end of the pull rod, and the dowel screw is connected with the nut. The multifunctional die-dismounting pull hammer has a simple structure. During the process of die dismounting, the force application point is transferred onto the sleeve of the pull hammer, and to-be-dismounted parts can be ejected out with no hole punching of an original die required. Further, due to the transfer of force application point, efficiency is greatly improved and labor intensity of workers is reduced.
Description
Technical field
The utility model relates to the die assembly apparatus field, is specifically related to a kind of multifunctional mold dismounting and draws hammer.
Background technology
Injection forming mold can wearing and tearing in various degree occur in use procedure, and new mould also may go wrong in initial die trial, and this all needs mould is carried out to secondary operations, and mould is taken apart, is repaired a die.Be at first by dynamic model and cover half separately as the step 1 of dismounting mould, will move respectively, the trip bolt of cover half unscrews, and then gets pin, with extracting tool by mould main plate pull down; Next is to pull down running gate system from solid plate, from moving platen, pulls down ejection system, breaks each part of ejection system, extrudes the parts such as core from fixed head, while having undercut to take out concentric mechanism, pulls down each part of undercut mechanism; The dismounting of the small-sized accessory of Luo line is arranged for mold insert, middle holder department etc., and in the process of tearing open, due to the bad stress point that finds, traditional method for dismounting is that it is rapped with hammer, make it loosening, then back-out, or in the situation that do not affect mould use and function, hole on mould, will eject.These methods are not only consuming time but also consume power, also mould itself had to damage in various degree.
The utility model content
The purpose of this utility model is not only consuming time but also consume power and provide a kind of simple in structure and labour-saving multifunctional mold dismounting to draw hammer when overcoming in prior art the dismounting mould parts.
In order to achieve the above object, the technical scheme that the utility model adopts is as follows:
Hammer is drawn in a kind of multifunctional mold dismounting, the dowel screw that comprises pull bar, is enclosed within the outer hollow circular cylinder sleeve of pull bar, is fixed in the nut of pull bar upper end, the nut be connected with the pull bar lower end and is connected with nut.
There is tap above-mentioned pull bar lower end, by nut cylinder lever connecting rod and dowel screw.
Above-mentioned sleeve diameter is less than the nut external diameter, and sleeve diameter is less than the nut external diameter.
Above-mentioned dowel screw is formed by two screw weldings, and one is connected with pull bar, and other end is connected with the part that will dismantle.
The beneficial effects of the utility model: compared with prior art, the utility model is simple in structure, when the dismounting mould, makes the point of application in unloading process transfer on the sleeve that draws hammer, without punching on original mould, the part that dismantle can be ejected; And, due to the transfer at application of force place, improved greatly efficiency, alleviate labor strength.
The accompanying drawing explanation
Fig. 1 is the structural representation that hammer is drawn in the dismounting of the utility model multifunctional mold.
Fig. 2 is that hammer side structure schematic diagram is drawn in the dismounting of the utility model multifunctional mold.
The structural representation that Fig. 3 is the utility model dowel screw.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further described in detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Hammer is drawn in a kind of multifunctional mold dismounting as shown in Figure 1 to Figure 3, comprises pull bar 2, is enclosed within the outer hollow circular cylinder sleeve 3 of pull bar 2, is fixed in the nut 1 of pull bar 2 upper ends, the nut 4 be connected with pull bar 2 lower ends and the dowel screw 5 be connected with nut 4.
There is tap pull bar 2 lower ends, by nut 4 cylinder lever connecting rods 2 and dowel screw 5.
Dowel screw 5 is formed by two screw weldings, and one is connected with pull bar 2, and other end is connected with the part that will dismantle.
While using this multifunctional mold dismounting to draw hammer, the part that will dismantle is connected to dowel screw 5 and connects, and by sleeve 3 mobile part that makes on pull bar 2, produces pulling force backward, then part is taken out.In order to prevent sleeve 3 landing from pull bar, the internal diameter of sleeve 3 is less than the external diameter of nut 1 and nut 4.
The foregoing is only a preferred embodiment of the present utility model.What deserves to be explained is; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle; can also make some distortion or improvement to the utility model; the equivalence of doing according to the described structure of the utility model patent claim, feature and principle therefore all changes or modifies, and these features all belong to the scope of the utility model patent application protection.
